6 Claims. (Cl. 242-157) I i This invention relates to a strand guide of the general type used for winding yarn, thread, or other fibre materials from a supply. spool orbobbin .onto' a cone or receiving package, and has for its purpose to afford a guide eye of practical and efficient light weight construction in which the strand-engaging surfaces are resistant to wear and abrasion so as not to be affecte ld'by continued usage. l

A more particular purpose of the invention is to afford a guide eye consisting of a metal supporting body of minimum weightand provided with abrasion-resistant elements or surfaces at thej'poi'rit's where thefstrand is in frictional engagement with tlie; eye, thus: protecting the refractory abrasion-resistant elements against breakage. v e v A further object of. the invention is t'o afford a strand guide that, can be economically producedf'and consists United States Patent 0 to and spaced from the first mentioned side portion 3. The side portion 5 terminates in an offset terminal portion 6 spaced from and parallel to the side portion 4, affording an opening 7 through which a strand can readily be inserted into the guide eye between the opposite parallel side portionsQ The metal supporting body is preferably elongated approximately as shown, having a length considerably greater than its width in order to accommodate itself more readily and without interference with other parts of the winding mechanism as the wound cone increases in diameter, and the metal supporting body is mounted on a metal base or post 8 that may be of greater length than the eye and is readily attachable to and secured in a. sleeve 9 formed at the'upper end of a conventional supporting arm 11 mounted for pivotal movement toward and away from the cone or yarn body onto which the .strand 'is wound as usual in this type of machinery.

The posts terminates at its upper end in a flat plate 12 that is secured in any suitable fashion as by soldering or otherwise to the under surface of the lower, loopshaped end 2 of the metal body, and 13 designates an abrasion-resistant element or tip that overlies the top surface of the loop-shaped end 2 of the metal body and the plate 12 on the under surface thereof. The abrasionresistant element 13 includes a projection 14 of reduced of a metalsupporting body portion of novel and meritorious form and having abrasion-resistant surfaces or elements at opposite ends of the metal body arranged to receiveand direct'the stand'ofllyarn or other material as it travels through the guideeye'inengagement with opposite surfaces thereof at the ends.' I

I Still an additional purpose is to aiford in. conjunction with a metal supporting bodywith loo'pfshaped ends, novel and improved forms of abrasion-resistantelements orsurfaces-and attaching them to ther'net'a l b'ody ina manner that insures their rigid and permanent connection withthebody. y 1

, To these and other ends, the inventionfeonsists in the construction and arrangement .of parts that' will'appe'a'r clearly from the following description when read in conjunction with theaccompanying drawings, the novel features being. pointed out in the claims following the specification. v

In the'draw ings: 5

Fig. 1 is a view in side elevation illustrating a preferred embodiment of the invention and showing the. strand guide in the operative position it assumes "in contact with abody'ofyarn being wound onto a co'nef 3 Fig. 2 is atop plan view of" the guide eyepwith'the base partially broken away;

Fig. 3 is a bottom plan view of the same; Fig. 4 is a sectional view on line 4-4 of Fig. 2 looking in the direction indicated;

Fig. 5 is a sectional view on the line 5--5 of Fig. 4

looking in the direction indicated, and

Fig. 6 is a detail plan view of the metal supporting body of the guide eye.

Referring more particularly to the drawings in which like reference numerals refer to the same parts throughout the several views, the guide eye consists of a metal supporting body formed of a rod or stiff wire of approximately ",in diameter or less and preferably of cylindrical cross-section, said wire being bent upon itself to afford two loop-shaped or curved ends 1 and 2, which are connected on one side by a straight continuous side portion 3 and on the other side by side portions 4 and 5 parallel diameter extending between the side portions of the loop-, shaped end 2 of the metal body into engagement with the plate 12 and'securely attached to the plate 12 and to the loop-shaped end of the'body by soldering or in any, other. suitable fashion. The abrasion-resistant element or ,tip; 13 is formed with a groove 15 through which the [strand passes and against which it engages as it is fed to the cone on which it is to be 'wound, the abrasion-resistant element,

13 being formed of any suitable material for the purpose and preferably fire-hardened in accord with established practicesin the manufacture of such abrasion-resistant. material. The abrasion-resistant element 13 entirely covers the upper surface of the lower loop sha'pedend 2 of the metal body, so that as the strand of yarn indicated at 16 travels upwardly, it passes over the curved surfaceof the abrasion-resistant tip which defines the groove 15 and thence through the space afforded between opposite side portions of themetal body to where it passes under the upper end of the guide eye, as indicated in Fig. l.

The metal body is protected at its upper end by a laterally curved abrasion-resistant element or tip 17 which is provided with a hollow interior of laterally curved formation so that it fits closely around and over the upper. curved loop-shaped end 1 of the metal body and is at tached thereto by suitable solder 13. The abrasionres'istant element or tip 17 is provided with a groove having a curved bottom, and as the strand 16 passes from the lower abrasion-resistant element 13 through th e, guide eye, it travels thence through the groove 19 ofthe upper abrasion-resistant element under the latter and onto the cone. In this fashion, the strand is wound onto'the cone without contacting any portion of the metal supporting body of the guide eye, all friction and wear being taken by the abrasion-resistant elements 13 and 17, and the structure can be used indefinitely since all wear is absorbed by. the abrasion-resistant surfaces which are of such material that they are not affected by the friction of the strand passing in engagement therewith.

By producing the supporting body of the guide eye of light weight metal stock and protecting the ends of the metal body with abrasion-resistant material, it is possible to make the guide eye of minimum weight and of elongated form or any desired length and thus adapt it to a more efficient operation and so as to coordinate more successfully with large diameters of cones than guide eyes as heretofore constructed. The structure ena'bles producing a guide eye that is stronger, of considerably less weight, of lower manufacturing cost, and having abrasion-resistant surfaces that are protected and less likely to be broken, than devices heretofore available for thepurpos'e, while the guide eye of elongated form avoids interference with other parts of the winding mechanism as the diameter of the cone increases.

While the invention has been described with reference to the particular structure shown, it is not restrictedto the details herein disclosed, and this application is in-' tended to cover such modifications or departures asmay come within the purposes of the improvement or the scope of the following claims.
